vented certain new and useful Improvements in Liquid-Fuel Burners. of which the following is a specification.

This inventio-n relates to a vertical liquid fuel burning` device in which liquid fuel. such as kerosene or other oils is used. and said burner is especially intended for heat ing purposes, cooking, and steam boiler furnaces. The characteristic feature of said burner consists in that it is combined with a steam injector in order to increase the draft and to facilitate supp-lying and mixing' the kerosene (or other) vapors with the air, thus securingl a complete combustion of t-he fuel and a high efficiency -of the burner.

The accompanying' drawing shows a per-A spective view of the burner the shape and dimensions of which may vary, of course,-

according to the especial use to which sait burner is to be applied.

In the drawing, 1, 2, 3 and 4 are tubular supports through which water and fuel and their respective vapors are conducted in the manner described more fully hereinafter. Said tubular supports are closed at their lower ends and support two superposed ring shaped tubes 5, 6. The upper annular tube 6 is fixed on the tops of the tubular supports 1, 2 and 4 while the lower, smaller one, is located between the tubes 1, 2 and 4 and rests on the tubular support 3 with which it is connected. The interior of said lower ring 5 communicates by means of a small connecting tube 7 with the interior of the support V1. The, central space surrounded by the ring 5 is provided with a flat disk 8 which is secured to the lower peripheral surface of said ring. Below said disk 8 and axially disposed with respect to the same is provided the burner proper, whichl com-l prises a short vertical tube 9 closed at its lower end and communicates b v means of the horizonta'l branch tube 7l0 with the tubular support 3. f Centrally Iwithin the tube 9 is disposed a smaller tube 11 which is coniiected with a. horizontal tube 12. Said tube is in turn connected at one end with the support 4 while its opposite free end 13 is closed. The tube 9 is surrounded by an air-supply duct made of two truncated cones 14, 15 connected together, at their small ends. The funnel 14 is fixed to the horizontal tube 10 which maintains both truncated cones "14. 15

such a manner that thefjuncture of's'aid funnels is level with the upper end 'of the tubes Qandll.

an inner vertical` cross-partition16 "which is located between the'tubes 2v and 4 while the lower ring 5 is pro-vided with` a similartpartition 17 located between the tubesy 7vl'ancl 3. The tube 1 is provided nearitslowerend witha feeding tube 18andabove sai'dfeed-- ing tube with an interiorly:arranged and upwardly directed nozzle 19. The tubular support 1 is closed above the tube '7T b v a horizontal partition 20.v Thefsu'pporting tube is provided near its lower e'ndw'ith a feeding pipe 21 above which is'arranged, inf side said support 2, an'upwardlzv directed nozzle 22. u

The above describedburner works `as folknown way. Then .the fuel-is admitted through the tube 18. Said fuel ,risps into the tubular support 1 and flows through the horizontal tube 'l into' ,t-hefliollo'w -ringd flowing back and flow ythrough the support 3 and the tubes 10 and 9. intotlie burner proper. Owing to the .partition 17 ,fthe fuel and its vapors are obliged ,to How through substantially the whole length offthering 5. On the other side the tube 21 supplies water, which rises through the tubular support '2 and enters the upper ring 6 in which it is vapor-ized and, after having traveled nearly through the whole ring. the steam escapes through support 4, horizontal tube 12, and vertical central tube ll'ofthe burner. The necessary air for the combustion of the fuel vapors enters the'y burner in the direction of the arrow 23 through the lower truncated cone 14. It is to be understood that, since steam escapes through tube 11` the latter acts i as 'a spray nozzle, considerably increasing the draft of the burner and providing fur- -thermore a thorough mixingof fuel vapors and air, this securing a complete combusitioni and increasing` the efficiency of the burner.

concentrically around the; tubes 91and1'1 in' The upper tubular ringt` is provided with lows: Ring 5 is preparatorily heated in. some Having now fully described my said inwhere it becomes vaporized. The burner is f poi-s are prevented by the nozzlegl, from 11 l. In a device of the character described,

the combination of an annular tubular vaporizer, a plate disposed within the same and connected thereto, a burner located be low the plate, whereby1 the flame is deiiected around the outer edge ot said vaporizer, means for supplying ,tuel to the vaporizer, means connecting the vaporizer and burner, an annular tubular member disposed" above the vaporizer and of greater diameter than with water. and means for connecting;l said member and the burner. t

2. In avdevice of the character described, the combination ofa plurality of vertical tubular supports forming' a frame for said device as well as the'supply ducts for fuel and for water, a lower smaller hollow ring connected with said fuel duct. an upper hollow ring` connected with said water duct, a burner on said tubular frame beneath both said rings vcomprising; two concentrically disposed spaced apart pipes, a connection between the outer of said pipes and the lower ring', for supi'ilving said pipe with fuel vapors, a connection between the central pipe of said burner and the upper rinp; for supplying' steam to said central pipe, and two t-runcated'fcones concentrically disposed with respect to vsaid burner, the small ends of said cones beingjoined at substantially t-helevel of the upper ends of the burner pipes. v

3. In a device of the class described,`thc combination of a plurality of vertical tubular support-s forming' a frame as Well as supplying' ducts for -l'uel and for water, nozrles located in said supply duct-s for fuel and water, a lower smaller hollow ringconnected with said fuel duct, a partition on the inside of said lower smallerring' adjacent the point where the fuel duct enters, a central plate secured on the bottom part ol secure l said smaller ring :t'or

l i l l l l receiving` the heat of the flame and transmitting the heat by conduction to said ring', an upper larger hollow ring' connected with said water duct, a partitionon the inside oit' said larger ring, adjacent the point where the water duct enters, a burner located below the central plate con'iprising t-wo concentrically spaced apart pipes, a connection between the outer of said pipes and the lower smaller ring for supplying' vapor thereto, a connection between the central pipe of said burner and theA uptfhe same, means for supplying' said member g l l l l l I 1 per larger rinfaY for supplying steam thereto, and two oined truncated cones concentrically disposed with respect to the said pipes, the meeting` ends of; said two truncated cones being substantiallv level with the upper ends of beth pipes of the burner.
